Imagination it turns out is a great deal like reporting in your own head. Here is a paradox of fiction-writing. You are crafting something from nothing which means in one sense that none of it is true. Yet in the writing and perhaps in the reading some of a character's actions or lines are truer than others.
To me it all comes down to things being character-driven. It's hard for me to look beyond that. CG and all this cool stuff - so be it. But to me it pretty much begins and ends with character-driven plots rather than technologically-driven plots.
